What is Lumen?

Lumen is a unit measurement for the total amount of light emitted by a light source. It measures the brightness of the light that we perceive. The higher the number of lumens, the brighter the light. 

As lighting becomes more and more energy-efficient, the same number of lumens is being achieved with lower and lower wattages. 


What is Watt?

Wattage, on the other hand, measures the amount of energy that a light source consumes. It tells us how much power a light bulb uses, and not how bright it is. In general, the higher the wattage, the more energy the light bulb consumes. However, this does not necessarily mean that it produces more light. Older incandescent bulbs require higher wattage to produce the same amount of light as newer LED bulbs, which are more energy efficient.


Take Away

Using lumens and watts together, we can determine how energy efficient a light bulb is.

To compare LED bulbs with other types of light bulbs look at the packaging. You’ll see the number of lumens produced as well as the wattage of the bulb. Compare the lumen numbers to see if the lightbulbs will give off a similar amount of light, then look at the wattage requirements to see how much energy each bulb will use. To choose the most energy efficient bulb for your needs, find ones that have the light output that you need, then choose the one that has the lowest wattage.

For example, a standard 60-watt incandescent light bulb produces around 800 lumens of light. In contrast, and LED bulb with the same brightness may only require 10-12 watts of power.
